X'Vhen the discharger or fan is recylinder causes the straw to be spread latervolvcd rapidly in the direction of the arrow ally before it falls upon the top of the stack.

In operation the dellector is raised somewhat above the position shown in Fig. l, and it is revolved continuously by the straw, which impinges against its lower side. The straw is deposited in different places on the stack by raising and lowering the deflectorframe.

' This elevator and stacker can be used to raise hay and many other light substances, as well as for raising straw.

Vhat I claim is- 1. In a pneumatic stacker, the combination with a discharge-pipe, of a frame carried by the said pipe, and a revoluble cylinder journaled in the said frame and operating to deflect the straw, substantially as set forth.

2. In a pneumatic stacker, the combination, with a discharge-pipe, of a frame carried by I[he said pipe, and a barrel-shaped cylinder journaled in the said frame, said cylinder being larger at its middle portion than at its ends and operating to deflect and spread the straw, substantially as set forth.

3. In a pneumatic stacker, the combination, with a discharge-pi pe, of a frame hinged to the said pipe and provided with means for raising and lowering it, and a revoluble cylinder journaled in the said frame and operating to deliect the straw, substantially as set forth.

4. In a pneumatic stacker, the combination, with a discharger-casing provided with an opening on one side, of a hood covering the said opening and provided with an inlet at its lower part and an outlet above the said inlet, and a discharger journaled in the said casing, substantially as set forth.

5. In a pneumatic stacker, the combina- 40 tion, with a discharger-casing provided with an opening on one side and a lip at the bottom of the said opening, of a hood covering ilie said openingv and provided with an inlet below the said lip and an outlet above the said inlet, and a discharger journaled in the said casing, substantially as set forth.

6. In a pneumatic stacker, the combination, with a discharger-casing provided with an outlet arranged to one side 0f the casing, of a discharger journaled in the said casing and provided with blades having forwardlyprojecting lips on their front edges and rearwardly-projecting lips on their rear edges`r whereby the air is forced spirally through the said outlet, substantially as set forth.

7. In a pneumatic stacker, the combination, with a straw-chamber, of a dischargercasing having its inlet and outlet arranged upon the same side of it and within the said chamber, and a discharger journaled inside the said casing, substantially as set forth.

S. In a pneumatic stacker, a discharger or fan provided with blades having forwardlyprojecting curved lips on their front edges and rearwardly-projecting curved lips on their rear edges, and a disk arranged on the same side as the rear edges of the blades` substantially as set forth.

0. In apneumatic stacker, the combination, with a discharger-casing having a discharge-opening formed through one side Wall thereof and extending to the periphery of the said casing, of a discharger journaled inside the said casin g, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

LEMUEL D. PARMLEY.
